getaddrinfo failed

i am working on a script which needs to have a link back to our site.

Some people are removing the link to the script in the skin of our script

We have the following information with us in our database

client_name
client_url
client_status

i run a foreach loop after fetching data from the table
open the url using fopen and check for occurence of a link to "http://www.domain.com"

$urlContents = file($client_url);
for ($i=0; $i<count($urlContents ); $i++) {
$text = $text . $urlContents [$i];
}
if (eregi($client_url, $text)) {
true
}
else {
false
}

this part is working

i need to check for 404 errors on invalid domains

if i run this script when a domain is down i get this error

Warning: file() [function.file]: php_network_getaddresses: getaddrinfo failed: No such host is known. in validate.php on line 24

line 24 is $urlContents = file($client_url);

any way to handle this error

 

How do you exactly want to handle it? If the host is down you can't do anything...

 

i figured it out

use @file to suppress the error message.
